HRM that shows % of max HR?

I've used a HRM once a few yrs ago and found it worked very well to make the ride managable - we were going up a long mountain - gradual climb and using the HRM i was able to keep myself from blowing up. i"m coming back to riding again and want to use again the HRM to make keep rides sustainable. I then noticed the screenshots of the Edge 500 showing % of the max HR. I thought that would be quite useful instead of using the heart beat numbers.

The polar FT4 also has a min to max range and the current heart beat is indicated within that range.

Just about any of Garmin's fitness models with a HRM will give you that as an option for a field. Pretty sure that most HRM's will do it, too, because yeah, it is a more useful training number than absolute HR.

i've downloaded the manual for the edge 501 but no where does it show how to display the % max HR. I don't think displaying % max HR is that common - that was the first time i saw it on the screenshots of the Edge. Most units display the HR beats.

HRM that shows % of max HR?

Thanks NateHawk - i've now read the Polar Ft4 manual and it does allow you to display in % max HR. Maybe i'll get that instead as i don't need the GPS functions of the Garmin Edge units - i already own the Garmin GPSMAP 62s.
